Forms Data Controls :: Access Gridview Column 2 And For Each Row Replace Text
Mar 31, 2011
i want to access gridview collumn 2 and for each row replace the text that is there with a "*" because its a password fields so instead on show the pass hide it with * so its more or less this but... see comment line
I have a gridview which is binded to a Sqldatasource. I would like to replace a column data field value to 'Not Applicable' if that column has got a value of 2 in database.
I would like setting up my GRIDVIEW to display an image in of the columns instead of a text where deathmarker column contains a specific word (Y).I got it working to show an image in every row, but i need a way of filtering this so it should only appear if the deathmarker column is populated with the letter "Y".below is the asp.net code
I have big problem I have a table where the column is "Enabled" datatype = bit.
In this column I have data True / False. The show GridView column 'Enabled'. Problem is, as everywhere in this column, write True / False. How, in view of this information in the GridView displayed: True = Verified, False / UnVerified GridView, column is "Enabled"
Column Enabled: No False No True Column Enabled I want this Unverified Verified
It should probably change the text, or something like that.
As per my requirement, I am getting CompID, Company Name and URL from SQL database. I want to display just CompName and URL in gridvew. So, I need to hide the CompID in gridview. One way I can do BoundField field Visible to false but I need to retrive that compID id when user selected any of the row. if I set visible to false user wont see any compID in gridvew but I want access the selected compID also using SelectedRow.Cells[1].Text..
I have seen a lot of things on the net on this but nothing seems to work. I have a GridView with name and other information on files stored in a database but also on a Server. I display the gridview with the files and the user selects the file to delete (row) by hitting the command field for Delete. I have an event on the gridview for code behind. Here I want to access the file name for the row selected, to be able to include it in the File.Delete statement.
Even before this I want to display the selected file name in a label back to the web page. I have tried everything including findcontrol selectedValue, etc. Nothing is working. I either get complier error, or nothing is displayed in label. If I let it go the the File.Delete step I get access error becasue there is no file name. HELP. here is screen shot of the gridview. Ignore the download button for now. That is my next headache to figure out. So based on the screen shot I want the value of log_doc from the gridview. It is in a column called file_name
File ID File Name Log Upload Date Uploaded By Download Delete 3
I would like to enter a name into a textbox, click a button and find the name in my gridview name column , then move to and select that row in the gridview. How can this be done?
I have a 1-column gridview (and it must remain 1-column) which contains only text. My requirement is to prefix each row with an image followed by the text. The image may or may not be indented a bit, like an expanded child node in a tree.
I know a gridview renders as a table and I know I could put an image at the beginning of each row in a table (using a repeater, for example). But this is an existing app with a couple gridviews which need to be enhanced and I don't have the time to swap out the gridviews for repeaters.
i'm bindng data to gridview using bound field.one column of gridview is linkbutton.if the text is more than the cell width then the gridview width is increasing automatically.for ex if i have text like "microsoft asp.net forums" then it's displaying the whole text.but i need that text like "microsoft.....".how to display like this in gridview?
I've got a gridview on my page that gets its infomation from a database. One of the columns shows whether a news article is featured or not. It currently displays a 1 or 0.
I would like to change it so that it shows a tick icon if it's a 1, or a nbsp; if it's 0.
I have a merged column of firstname and lastname by "Select firstname + lastname from table" but when it appears in the gridview the header text of the column is "Expr1000". How can I change the header text of that merged column?, and I want to change its text into "NAME".
I want if the header of a particular column contains a word "S", the header and row turns red. I used following code to make header red and it works fine. How to make it such that the rows also turn red if condition is met ? I cannot hardcode in columns since the Gridview is autogenerate colums as data structure keeps changing.
Protected Sub GridView1_DataBound(ByVal sender As Object, ByVal e As System.EventArgs)Dim HeaderRow As GridViewRow = GridView1.HeaderRowFor Each c As TableCell In HeaderRow.CellsIf c.Text.EndsWith("S") Then c.BackColor = Drawing.Color.OrangeRed End If Next End Sub
I just hit the same problem as described here: [URL] - GridView paging with ObjectDataSource. I see the column headers but no data, and I know for a fact my method returns a DataTable with data in it.
I'm using a book to create a shopping site and need to change the following code so that the current dropdown list, of colour options, is replaced by just read only text. I'm a novice and despite best efforts I can't fathom it out. If anyone can change the code for me I would be extremely grateful.
The code below is the code-behind page for a Product List page where I want each product displayed to also display its colour options as just text (I don't need the shopper to select a colour choice until they click through to the detail page)
using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using System.Data; public partial class UserControls_ProductsList : System.Web.UI.UserControl { protected void Page_Load(object sender, EventArgs e) { PopulateControls(); } private void PopulateControls() { // Retrieve DepartmentID from the query string string departmentId = Request.QueryString["DepartmentID"]; // Retrieve CategoryID from the query string string categoryId = Request.QueryString["CategoryID"]; // Retrieve Page from the query string string page = Request.QueryString["Page"]; if (page == null) page = "1"; // Retrieve Search string from query string string searchString = Request.QueryString["Search"]; // How many pages of products? int howManyPages = 1; // pager links format string firstPageUrl = ""; string pagerFormat = ""; // If performing a product search if (searchString != null) { // Retrieve AllWords from query string string allWords = Request.QueryString["AllWords"]; // Perform search list.DataSource = CatalogAccess.Search(searchString, allWords, page, out howManyPages); list.DataBind(); // Display pager firstPageUrl = Link.ToSearch(searchString, allWords.ToUpper() == "TRUE", "1"); pagerFormat = Link.ToSearch(searchString, allWords.ToUpper() == "TRUE", "{0}"); } // If browsing a category... else if (categoryId != null) { // Retrieve list of products in a category list.DataSource = CatalogAccess.GetProductsInCategory(categoryId, page, out howManyPages); list.DataBind(); // get first page url and pager format firstPageUrl = Link.ToCategory(departmentId, categoryId, "1"); pagerFormat = Link.ToCategory(departmentId, categoryId, "{0}"); } else if (departmentId != null) { // Retrieve list of products on department promotion list.DataSource = CatalogAccess.GetProductsOnDeptPromo (departmentId, page, out howManyPages); list.DataBind(); // get first page url and pager format firstPageUrl = Link.ToDepartment(departmentId, "1"); pagerFormat = Link.ToDepartment(departmentId, "{0}"); } else { // Retrieve list of products on catalog promotion list.DataSource = CatalogAccess.GetProductsOnFrontPromo(page, out howManyPages); list.DataBind(); // have the current page as integer int currentPage = Int32.Parse(page); } // Display pager controls topPager.Show(int.Parse(page), howManyPages, firstPageUrl, pagerFormat, false); bottomPager.Show(int.Parse(page), howManyPages, firstPageUrl, pagerFormat, true); } // Executed when each item of the list is bound to the data source protected void list_ItemDataBound(object sender, DataListItemEventArgs e) { // obtain the attributes of the product DataRowView dataRow = (DataRowView)e.Item.DataItem; string productId = dataRow["ProductID"].ToString(); DataTable attrTable = CatalogAccess.GetProductAttributes(productId); // get the attribute placeholder PlaceHolder attrPlaceHolder = (PlaceHolder)e.Item.FindControl("attrPlaceHolder"); // temp variables string prevAttributeName = ""; string attributeName, attributeValue, attributeValueId; // current DropDown for attribute values Label attributeNameLabel; DropDownList attributeValuesDropDown = new DropDownList(); // read the list of attributes foreach (DataRow r in attrTable.Rows) { // get attribute data attributeName = r["AttributeName"].ToString(); attributeValue = r["AttributeValue"].ToString(); attributeValueId = r["AttributeValueID"].ToString(); // if starting a new attribute (e.g. Color, Size) if (attributeName != prevAttributeName) { prevAttributeName = attributeName; attributeNameLabel = new Label(); attributeNameLabel.Text = attributeName + ": "; attributeValuesDropDown = new DropDownList(); attrPlaceHolder.Controls.Add(attributeNameLabel); attrPlaceHolder.Controls.Add(attributeValuesDropDown); } // add a new attribute value to the DropDownList attributeValuesDropDown.Items.Add(new ListItem(attributeValue, attributeValueId)); } } }
I have my data table generated dynamically binded to grid view. (Autogeneratecolumns true)
in my UI its displaying the column headers.
am not able to access it by grdname.HeaderRow.Cells[0].Text
am not able to get the names from the columns also.
since am binding the columns dynamically i am not able to get access to all the columns
and am able to get only 2 columns which i have mentioned in my aspx which are the command buttons edit and delete.
am trying to access all these in Gridview_RowCommand event. need to get the value in the (dynamic) column named Id for the row on which the edit or delete button is clicked. since it doesnt have a header am unable to access it bcoz i dont know the index of the cell too..
Is it possible to access textbox text properties from codebehind when gridview is edit mode? for example I can access label's text properties on gridview row databound event.
[Code]....
So I do not like use Text='<%#Eval("ColumnName")%' this method. I want to manage textbox text properties dynamcily codebehind when click the edit button on gridview. When I clik the edit button these code blocks runs
[Code]....
but rowdatabound event fires again and couldn't find label control. It looks for textbox control to bind data but I can not manage this step.
I have a gridview with databound fields with a checkbox for each row. Only the check box is not bound to any field in the database. I have a button outside of the gridview. By clicking the button, I am trying to get the values of the partyID fields for all the rows that have the check box checked.
Upon clicking the button, nothing gets displayed but no error either.
