Asp.net - Find Out Gridview's Selected Row Position?
Nov 22, 2011
I have a text box and button inside a panel , and I want to show this panel right next to gridview selected row , gridview is also inside another panel , is there anyway to find out selected rows position ? This is a asp. Net page and I am using vb.net . Panel can be replaced by div
I have an issue with maintaining scroll position.I am almost positive that I have everything set correctly. I have updated my web config...
<pages maintainScrollPositionOnPostBack="true"
and everything seems to work fine UNTIL....When ever my Gridview returns a lot of pages, like more than 50, sometimes upwards of 100 or more, I show 50 records per page. The farther into the Gridview, the more the scroll position is off.So what I am saying is that for the first 20 plus pages or so, if I scroll down the page to the point where the top rows have moved off the screen and I enter Edit Mode, the correct record remains in view on Postback.But if I am over say around 30 pages into the Gridview, the further in the worse it gets, when i enter Edit Mode I have to scroll back down to the location of the record that I selected to edit.
So say I have a listbox, and a treeview. I select(using multiselectextended) a bunch of items in the listbox, I then press a button and it sends those selected items to a teeview node and removed them from the listbox... I then modify the items, add more items, etc..after I'm done modifying them, how could I send the items from the treeview back to theyre original position in the listbox?
Here's the issue in a nutshell (I can elaborate if you feel it's needed). In a DataGridView I want to capture the value of the row's key column so that when the user clicks on a column header to sort the data, I can reposition to the row that was selected prior to the click. The problem is that the sorting itself, once it's done, fires the same events (RowEnter for example) that I used to determine my key value, so it sets my variable to a new value and now
I am trying to develop a HANGMAN game and i need to implement a button where the user can click on it to "buy" letters. So, i designated 2 text boxes (one visible containing stars and another one not visible containing the word that should be guessed), and i wrote the following piece of code so that once the user presses the button any of the stars will turn to the correct letter. My question is, i found the index of "*" and removed it, and now i want to insert the corresponding char with this index (WordInLetters). How can i find what char is at index "index" in vb.net?
Private Sub picBuyLetters_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles picBuyLetters.Click Dim index As Integer = txtWordinStars.Text.IndexOf("*")

I wanted to create a module / tool similar to MS word where user should be able to add controls, resize controls, drag and drop controls.Anyway, I have got lot of references on how to resize control, drag and drop add control etc...my main requirement is i need a way to add grid and should be able to add cells to it. When i resize the grid control, the cell height & width should get extended and compressed accordingly. Also i need to save position of the controls to a text file.Saving positon of other controls is easy but most importantly i need to save each cell position of the grid.
I wan't a method with which to find a string within another string. It should return the position of the first occurrence of the substring. (In VB 2008 !)
I need to find the first occurrence of a certain word's position in a textbox, on how to do this? Once I find out how I can get the position of the word i am searching for I can then pull the data I need from the textbox. I am using visual studio 2010 / visual basic.Since I have no clue where to start on this code, I will post what code i will be using to get rid of the data i don't need from the textbox.
Dim s As String = TextBox1.Text TextBox1.Text = (TextBox1.Text.Remove(450))i figure I can do this in a few steps to bring the searched info out of the textbox. I am open to other ideas on how to gather my data from the file or textbox. Here is what I have to do: Pull all of the players names from a replay file and put them in separate text boxes or even a listbox.
When I select a row from my gridview by clicking on a linkbutton called 'Modify' and is the last cell in the row. Using the code below I can retrieve the key value from within the GridView1_RowCommand sub and move to the modify screen with the correct data.
Dim r As Integer = e.CommandArgument GridView1.SelectedIndex = r Dim Company As String = GridView1.SelectedDataKey(0).ToString
[Code].....
When I try to access the first row it returns the first row value from the original Gridview and not from the re-ordered one.

I have a gridview which gets its input from a database with sql. There is a column with checkboxes in the gridview, so you can select which row you want to export. There is also a column that's called "Project Number". When you push the button "Export" the program should figure out which row is selected, get the project number from this row and connect to the database to get the data from the selected projectnumber. I already got the part where it gets the selected checkboxes. But I'm stuck at the part where it gets the projectnumber from the selected row. Must be something with Datakeys I think.
I want to find a particular ID in a DataTable, I am using a DataView to filter the results, but how do I know which row in the original table the filter view corresponds to? Any ideas? In know I could use LINQ but I don't think this would help either?
I'm looking for the actual index position in a given source string.I have the following string
"<a> <b>zyx</b> <b>wvu</b>
[code]....
I'm loading that string into a .NET XmlDocument object. Carriage Returns and Line Fees may be a factor here.
Dim xmlSearchText As New XmlDocument() xmlSearchText.LoadXml(SearchTextBox.Text) Dim selectedNode As XmlNode = xmlSearchText.SelectSingleNode(txtSearch.Text)
The following XPath Statement could be used to find the 3rd node:
a/b[.='tsr']
However, I need it to return a string index of 23 rather than the ordinal position of 3.
In RowCreated of the GridView i add following script to select a row:
Select Case e.Row.RowType Case DataControlRowType.DataRow e.Row.Attributes("onclick") = Me.Page.ClientScript.GetPostBackClientHyperlink(Me.MainGrid, "Select$" & e.Row.RowIndex) End Select
This works like a charm(i thought).But when i debug the SelectedIndexChanging and the following SelectedIndexChanged events, i observe that the RowState of the selected Row switches from normal{0}/alternate{1} to 3 instead of selected{2}. This occurs between SelectedIndexChanging and SelectedIndexChanged. Why does this happen? The next time i programmatically set the selectedIndex(f.e. after a new row was created), i have two rows that are selected and no (un-hacky) way to deselect the old in RowDataBound, because of the invalid RowState of 3(should only be 0,1,2,4 or 8).
I'm trying to sort records in the gridview right after a radio button is selected. My approach is with the dataview, but because the dataset variable doesn't survive a round trip to the server, I don't know how to make this happen.[code]
I am trying to make a webpage that has a list of items on 1 page which is displayed in a gridview that has the auto generate selected button enabled, they can click this button and it loads the item into a collection which i have stored in a session. On another page the session containing the items they selected gets displayed in a gridview. [code]...
I want to change the text of two labels based on the the selected row of a gridview.I keep getting an error that says the public member row does not exist on linkbutton
Protected Sub LinkButton1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Dim LinkButton1 As LinkButton = DirectCast(sender, LinkButton) Dim tour As Label = CType(sender.Row.FindControl("label2"), Label) Dim depart As Label = CType(sender.Row.FindControl("label3"), Label)
I have a button on the page and a gridview with checkboxes on the first column. The gridview is bound to a List. On buttonClick, I need to retrieve the underlying bound data item (MyEntity) for each selected row. How can I do this? I can't simply recreate MyEntity based on the gridview columns, because I am not displaying all the fields of MyEntity. I need a way to get a hold of MyEntity based on the key (MyEntityId).
I have a GridView with image buttons for selecting rows. I am using an OnRowDataBound event to color selected rows Blue:
e.Row.ForeColor = System.Drawing.Color.Blue
Now that works great as long as I don't set a color either in the CSS stylesheet or on the grid Items themselves. If I do that, then all rows are colored that color and I don't get my Blue selected rows color for selected rows. I would like to color the text in the grid something other than black.
I have a gridview and i am trying to determin when the selected gridview datakey value is nothing then set a serrion variable to 0.[code]Object reference not set to an instance of an object. on the 1st line.
even Word Pad, when you scroll your Caret (the I-beam for browsing through text) through the text, in the font combobox, the font of the text you are browsing through will be displayed, and when you scroll your caret through a different font, the font will be changed. If you're confused, look at attatched picture.
I cannot seem to find a caret position changed event on the normal richtextbox control - and if anyone can show me a custom component with this it would help me a huge amount.So my basic question is how can i replicate the formentioned function in my own VB.NET program.No code is necessary just constructive suggestions, or links to other projects would be welcome.
