Forms Data Controls :: Changing Value In Gridview Row?
Dec 13, 2010
I have a question, I have a gridview that shows a red balloon as imagebutton in one of the cells. Now i want to be able to let a users press the button, write a value in a record in the database and then change the red balloon to a yellow one. When the user wants (at any given time) wants the undo the value again the record should be rewriten again and the yellow ballon should be red again. Any tip is more than welcome :)
First off, sorry if this is in the wrong section. I have a gridview that loads from a SQL database. It has three columns, the first being a template column with a checkbox, the second being a name from the database, and the third being a field from the database related to that name. (the third column is empty). I want to be able to click on the check box in each row, and automatically have the third column populate with data that the user can select from a drop down list at the top of the screen or something. I am using VB, and I basically just need a way to make this checkbox, add a value from somewhere into the database. (Also, I know that I can just use Edit in the gridview to change data, but there will be a long list, and that way gets quite time consuming) I hope this makes sense, if not I can try rewording it.
I have a gridview bound to a SQL Select statement. I want the binding of one of the columns to depend on one of the values in the database record. For example, say I have a SQL table containing FirstName, LastName, ShowFirstName.
I want a the Name column in my Gridview to be bound to FirstName if ShowFirstName is 1, and bound to LastName if ShowFirst Name is 0.
I have made a gridview by assigning a sqldatareader object to it to display records....but i want to change the headertext of each column.i dont want the default name stored in the database how do i change the headertext?
I would like to change color of the gridView depending on the value from table that is bounded to the grid. I actually don't show this value on the grid. I tried by using additional field with visible=false, but the cell is string empty in this way. I don't know how to solve this in some other way?
I used this code, but as I said the value is empty:
Is it possible to solve this by getting value directly from bounded table and not from rows cell?
When I try to change a page on my gridview, I keep getting this error: Index was out of range. Must be non-negative and less than the size of the collection. How can I fix this? The line the error highlights is the one below:
Nw i want to change the TempPwd checkboxfield from another aspx file namely NewUserLogin.aspx, So is it possible? The idea behind doing this is, as soon as the user enters a new password in the NewUserLogin.aspx page, the checkboxfield in the GridView of CustomerSetup.aspx file should be unset.
I'm attempting to bind multiple datasources to a single Gridview. Can someone direct me on how to change the below <%# Bind("") %> programatically in the code behind. For example, change "HRID" to "PayrollID" to account for a different column. the dataSource binds to the Gridview so the Rows will not be created yet.
I know how to accomplish this with a boundField, but I'm having issues with setting the text of the label in the ItemTemplate.
This is an ASP.NET 3.5 project being created with VS2008. One page contains a gridview with six columns. One of the columns displays standard, 17 character , Vehicle Identification Numbers (VIN). The VIN numbers display normally when the page is rendered. However, when the gridview is exported to Excel, the VIN numbers change. For example, in the gridview, the VIN might be 12345678912345678But when the gridview exports into Excel, that same VIN becomes 1.23457E+16The value of that Excel cell changes to 12345678912345600, changing the last two digits from 78 to 00. It does this for every VIN in the gridview table.I did some Googling but couldn't find anything specifically on this issue. Has anyone seen it before? Is there a way to format the column in the gridview so that Excel will accept it as literal text? I tried programmatically adding a style called 'text' to that column but that had no effect on the outcome. All of the other columns are behaving normally.
im building a simple message messenger web application, i currently have a column in my database dedicated to the status of a message. Its bound to the third column in a datagrid.
After converting the column to a TemplateField and using a Label to fetch the data how do i change the text from the database to a small message, e.g. if the data in the database (as an interger) is 0. how do i change the interger to a string to display "UnRead". Do i need to do this during the databinding call or after the grid has been databound?
I know it would be easier to use a boolean and checkbox control but the interger column represents more values than true or false.
I have a gridview which i have enabled paging. When i select a page in the footer, the page postbacks, and I lose all data.I am lost on how to enable paging and maintain the data in the table.I manually insertthe information into a datatable then bind because of the way i have to get the information.Here is what I have so far: [Code]...
I have a stored procedure that returns a dataset with a different number of columns and different column names depending on user input. How can I use this with a GridView? Normally I define the columns beforehand in a static fashion, but, have never done a dynamic dataset like this.
I have a gridview that populate hyperlinks on a page. When i click on it it redirect to another page but when I go back one page it doesn't color the visited hyperlink. Does the gridview not support that or something? It works on the rest of my site. I tried adding CSS to it and still the same. This was my CSS:
I'm developing a bilingual web site, and therefore, I'm changing the text of the headings and the select buttons of my gridviews. I just discovered that if I set some code like below in the rowdatabound event of the gridview, the "linkbuttonish" headings get replaced by unclickable text. Thus, sorting the gridview is suddenly not working. What should I write instead?
If Session("lang") = "en" Then If e.Row.RowType = DataControlRowType.Header Then e.Row.Cells("name").Text = "Given name" End If End If
I guess that I should write something else than "e.Row.Cells("name").Text" to still have the click-behaviour, but I don't know what. The same question arises for the select linkbutton in a cell of the gridview's datarows.
What I have is a command column with 2 link buttons, Review and Update. The Review link will show a more in depth look at the record (pretty much a detailsview) The Update link will allow the user to edit a few select fields. The Update link works fine, because I put the code in the GridView3_SelectedIndexChanged event. When I click the Review link (which has code in the LinkButton1_Click event), there is no data from the Selected row, because the row is not yet selected. Is there a way to trigger the selection BEFORE the button click event? It seems like this should be easy, but I haven't needed to do this before.
I have a grid view which is populating with a data source through databind. And the Datasource is list of objects.Now when the user selected a row I want to get the object of that row. I'm trying to get the row like this.
GridViewRow r = gvTruckCarrier.Rows[e.NewSelectedIndex]; DataRowView drv = r.DataItem as DataRowView ;
but the drv value is null. Could any body tell me how to get the object of the selected row?
